We have a switch (Summit X440-24t) whose config appears to revert back to factory default whenever it experiences an abrupt power loss.
After a power loss, logging in with 'admin' user prompts the user with the canned preset messages (disable telnet? / SNMP? / etc). You can manually reapply any previous config settings, and it will actually persist through any number of 'reboot' commands (prompting you to save to primary.cfg after any change) issued from the command line. But, if it ever loses power, it will again revert back to factory default.
We then tried upgraded to a new firmware version (220.127.116.11) from our existing older version (15.1.0b20). The 'secondary' image partition becomes active, and will continue to use that partition after any number of 'reboot' commands. But like the config, it will revert back to the 'primary' partition with the old version in the event of a power loss.
Any help would be appreciated. Thank you!
